It does have AJAX/HTTP(s) ability; but it does NOT have any access to any of the NativeScript api. It also does not have any access to the Native iOS or Android api's. It is strictly a JS thread. In addition at this moment "ImportScripts" has not been implemented. It should be fairly easy to implement; and if anyone wants to do a pull request to implement this; I'd be happy to add it to the code that gets injected into the environment. 26 | 27 | If the device has more than one CPU; the Worker threads should not impact the main NativeScript thread. However, if the device only has one CPU; and depending on how busy you make the worker, it will impact the primary NativeScript thread. 28 | 29 | ## Installation 30 | 31 | Run `tns plugin add nativescript-webworkers` in your ROOT directory of your project. 32 | 33 | ## Usage 34 | 35 | To use the module you must first `require()` it: 36 | 37 | ```js 38 | const WebWorker = require( 'nativescript-webworkers' ); 39 | 40 | const myWorker = new WebWorker('~/web.worker.js'); // i.e. using the WebWorker variable returned by the require statement. 41 | ``` 42 | 43 | 44 | ## new WebWorker(data) 45 | ### data can be: 46 | - File path to a JS file (either relative `~/.../somescript.js` or full path `/..../somescript.js`) 47 | - Object with a `.HTML` - which allows you to pass in your own HTML file 48 | - please make sure the HTML is proper and not malformed. 49 | - Object with a `.script` - which allows you to pass in your own javascript code 50 | - Object can have its own custom `.baseURL`, otherwise defaults to the proper baseURL. 51 | 52 | ## NativeScript environment 53 | ### Events 54 | ####.onmessage(data) 55 | This will have the JSON object that was sent from the worker 56 | 57 | ####.onerror 58 | This will have any errors that occurred (this may be unreliable; as not all errors can be tracked properly) 59 | 60 | ####.onready 61 | This is fired when the webworker environment is ready to go. 62 | **This is NOT a standard webworker function** 63 | 64 | #### .executeJS 65 | This allows you to send some JS into the environment. 66 | **This is NOT a standard webworker function** 67 | 68 | ### Methods 69 | ####.postMessage(data) 70 | This posts the message into the webworker environment 71 | ####.terminate() 72 | This terminates the webworker environment; after this is ran; DO NOT attempt to continue doing anything on this webworker. 73 | 74 | 75 | ## WebWorker Environment 76 | ### Events 77 | 78 | ####onmessage(data) 79 | The function that gets any messages from the NativeScript environment 80 | 81 | ####onready() 82 | This function will get called if it exists once the webworker is able to communicate with the NativeScript host. 83 | **This is NOT a standard webworker function** 84 | 85 | ### Methods 86 | ####postMessage(data) 87 | The function you use to send message back to the NativeScript environment 88 | 89 | ####close() 90 | Terminates this environment 91 | 92 | 93 | ##Example: 94 | ### NativeScript code: 95 | ```js 96 | const WebWorker = require( 'nativescript-webworkers' ); 97 | var myWorker = new WebWorker('~/test.worker.js'); 98 | myWorker.onmessage = function(m) { console.log("Webworker said:", m); }; 99 | myWorker.postMessage("Hello"); 100 | ``` 101 | 102 | ### test.worker.js 103 | ```js 104 | onmessage = function(m) { 105 | console.log("NativeScript said" + m); 106 | }; 107 | onready = function() { 108 | postMessage("Hi"); 109 | }; 110 | ``` 111 | -------------------------------------------------------------------------------- /src/webworkers.android.js: -------------------------------------------------------------------------------- 1 | /********************************************************************************** 2 | * (c) 2016-2019, Master Technology 3 | * Licensed under the MIT license or contact me for a Support or Commercial License 4 | * 5 | * I do contract work in most languages, so let me solve your problems! 6 | * 7 | * Any questions please feel free to email me or put a issue up on the github repo 8 | * Version 0.0.3 Nathan@master-technology.com 9 | *********************************************************************************/ 10 | "use strict";
